C56877 Head impact count HeadImpactCt The count of head impacts measured by the biomechanical device The count of head impacts measured by the biomechanical devic Total number of exposure registered by device: Numeric Values

Total number of exposures registered - A single exposure refers to one occurrence of head impact/inertial exposure. The number of exposures registered refers to the total number of such occurrences over the duration of data collection. For example, if data collection occurred over a single American Football game for one player, and the player's head accelerometry device registered 30 impacts, the number of exposures registered would be 30. It is important to consider that for some sensor systems that they don't differentiate between actual play and things like halftime or water breaks. It can be challenging to measure true head impacts, not jumping up or down for example, unless that is the question being asked.
If any of the answers to b or d is yes, please enter the number of exposures after confirming with video or detection algorithm.
Exposures are confirmed in video - State whether the exposures indicated in a have been confirmed in video recordings of the activity. For example, if registered head impacts from an American Football game were observed in game video to occur at the times indicated by the data recordings, the answer would be yes. Select yes or no.
o If answer to b is yes, include description of video confirmation method or citation. Include a text description of the method used, or a citation of the method.
o Impacts are confirmed with validated impact detection algorithm - State whether the exposures indicated in a have been confirmed or detected by a validated method to detect exposure. For example, if registered head impacts from an American Football game were confirmed by a validated head impact detection algorithm to be head impacts (instead of spurious recordings), then the answer would be yes. Select yes or no.
o If answer to d is yes, include description of impact detection method or citation - Include a text description of the method used and validation performance, or a citation of the method.
